Well, for personal use only I think it is acceptable, for All others it is far less.

With time a fair number of models have been pirated mostly form men at war then Wot. None exhaustive list include FI 156 fiseler storch, Panzer II, Pak 36, PVII lowe, E-50, E-75 and 100 series, panther II. I forgot some for sure.

Here is an animated E-100 serie I reskinned. Camo is a bit fanciful but somewhat acceptable/credible.

Point you may have some difficulties depending your modding skill with sound and gun smoke.

If you plan to make your own mod and upload it, think about the PZVII Maus model which is afaik free to use.
